Overcome the limits of multi-contaminated industrial soils bioremediation: Insights from a multi-disciplinary study

Phytoremediation can be a promising and sustainable strategy to recovery Potentially Toxic Elements (PTEs) contaminated soils. However, at the field level, this tool can be limited by many issues. Herein, we combined native plant species with different cover type (mono and poly culture) in an in-field mesocosm experiment for the remediation of multi-contaminated soils from Bagnoli brownfield site (Southern Italy). We preliminary gain insights about the physical, chemical and biological features of the soils and subsequently induced a potential variation in the soil microbiome. We found that polyculture better respond both in terms of pollutant phytostabilization efficiency and from a stress tolerance perspective. Among plant species, Festuca achieved the best performance due to the overexpression of metal transporters able in both PTEs influx and sequestration from the cytoplasm. We achieved a site-specific bio-factory, which represents a strategy for the sustainable and relatively fast recovery of large contaminated areas

Towards Effective Social Insurance in Latin America: The Importance of Countercyclical Fiscal Policy

Latin America is a volatile, crisis-prone region, with limited and inadequate social insurance. Therefore, the long-term as well as the recent poor suffer significantly during crises. Furthermore, social spending is procyclical in the region, but less so than total spending, indicating that the effectiveness of compensatory social policies designed to protect those vulnerable to crises is constrained by adjustments during recessions. The causes of procyclical fiscal policy lie in the political constraints on saving during expansions, combined with limited creditworthiness during recessions, and enhanced by economic volatility and a low share of automatic stabilizers in the budget. We evaluate policy options to reduce procyclicality of fiscal policy, such as stabilization funds, fiscal rules and reform of budget institutions, and argue in favor of integrated policy proposals based on more country-specific analysis, such as the Fiscal Responsibility Law in Brazil
